Answer:
A business opportunity, in the simplest terms, is a packaged business investment that allows the buyer to begin a business. (Technically, all franchises are business opportunities, but not all business opportunities are franchises.) Unlike a franchise, however, the business opportunity seller typically exercises no control over the buyer's business operations. In fact, in most business opportunity programs, there's no continuing relationship between the seller and the buyer after the sale is made.
Although business opportunities offer less support than franchises, this could be an advantage for you if you thrive on freedom. Typically, you won't be obligated to follow the strict specifications and detailed program that franchisees must follow. With most business opportunities, you would simply buy a set of equipment or materials, and then you can operate the business any way and under any name you want. There are no ongoing royalties in most cases, and no trademark rights are sold.
Business opportunities are difficult to define because the term means different things to different people.
